Answer:
A
Explanation:
Natural selection occurs when an environment makes organisms with certain traits more likely to survive and reproduce.
Asexual reproduction results in no genetic variation (meaning differences in traits, also called divserity). Genetic variation must be present for certain organisms to be better suited to their environment, because in its absence all organisms share the same traits. This rules out B, C, and D. I hope this helps :)
Their child can not have a widow's peak, seeing as widow's peak is a dominant trait. They need two recessive alleles to have a straight hairline, meaning none can be inherited by the child.
Hope this helps.
Answer: The carbon cycle is the cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Steps of photosynthesis is absorption of light, electron. transport leading to the reduction, generation of ATP (adenosine triphosphate), and conversion of CO2 into carbohydrates.
Explanation:
metals (left side of periodic table) become positive ions so calcium would be the answer
If a plant cell had a mutation such that the cyclic electron flow is observed at a much higher rate, which photosystem is most likely mutated such that energy is absorbed at a lower rate?
PSI
PSII
Answer:
PSII
Explanation:
Non-cyclic phosphorylation involves both PSI and PSII. The process starts with the splitting of water and excitation of electrons of the reaction center of PSII upon the absorption of solar energy at the wavelength of 680 nm. Any mutation in PSII would not allow the non-cyclic phosphorylation to occur when only cyclic phosphorylation would occur. The process of cyclic phosphorylation includes only PS I. Its reaction center absorbs maximum light at 700 nm and is cycled back while supporting ATP synthesis. Therefore, if a plant performs cyclic phosphorylation at a higher rate and absorbs less energy, this means that mutation was in PSII.
